A standard zoological park at the base of Monsoon Palace hill - unless you have kids or are a dedicated wildlife-park completionist, this adds little over the Palace visit itself and the foreigner pricing (10x the Indian rate) makes it poor value.
Built beneath the Monsoon Palace hill, the park's construction began in 2004-05 under the Rajasthan Forestry and Biodiversity Project with financial support from the Japan International Co-operation Agency. It was formally inaugurated on 12 April 2015 by Union minister Prakash Javadekar, replacing the old, cramped Gulab Bagh zoo with a 36-hectare naturalistic habitat. It was among the first Indian zoological parks to deploy an augmented-reality app for visitor education about local flora and fauna.
